Maybe cURL isn't following redirections, have a look at CURLOPT_FOLLOWLOCATION (http://www.php.net/manual/en/function.curl-setopt.php)

if (substr($_SERVER['REMOTE_ADDR'], 0, 10) !== '192.168.1.') exit(); if (!preg_match('/^192\.168\.1\./', $_SERVER['REMOTE_ADDR'])) exit(); if (0 !== strpos($_SERVER['REMOTE_ADDR'], '192.168.1.')) exit();

$xml = file_get_contents('http://example.net/somexmlfile.php?url=msn.com');

$values = "87a003000c28"; $a=hexdec(substr($values, 0, 2)); $b=hexdec(substr($values, 2, 2)); $c=hexdec(substr($values, 4, 2)); $d=hexdec(substr($values, 6, 2)); $e=hexdec(substr($values, 8, 2)); $f=hexdec(substr($values, 10, 2)); echo $a^$b^$c^$d^$e^$f;

if (phpversion() >= 5) { echo '<table>', PHP_EOL; foreach (simplexml_load_string($xml) as $key => $value) { echo '<tr><td>', $key, '</td><td>', $value, '</td></tr>', PHP_EOL; } echo '</table>', PHP_EOL; }

__FILE__ - The full path and filename of the file. If used inside an include, the name of the included file is returned. dirname - Given a string containing a path to a file, this function will return the name of the directory.

Nope. (int) 'STRING' = 0; (bool) 'STRING' = TRUE;

There's probably nothing wrong with your code, failed to open stream: Permission denied Change the permissions on the file. http://www.dartmouth.edu/~rc/help/faq/permissions.html http://en.wikipedia.org/wiki/Chmod

You have no method called db_limiter(), you have a variable called $db_limiter and a method called page_limit_db() that returns $db_limiter. // using the variable, removed trailing parenthesis. while ($row_info = mysql_fetch_assoc($paging_system->db_limiter)){ // using the page_limit_db() method while ($row_info = mysql_fetch_assoc($paging_system->page_limit_db())){

You overwrite $row in your second while() loop. The second while() loop doesn't print anything, it just loops over the result rows and assigns variables until there are no more results. If you want to print all results you'll need to do so inside the loop.

<input type="text" value="<?php echo htmlentities($string_in_database, ENT_QUOTES); ?>" />

"Content-Length: " . strlen($some_string);

The double comma is the Scope Resolution Operator, in this case it's probably used to call the static method "getInstance" in the "Person" class. This method probably returns an object (instance of the class "Person"). The single arrow (->) is the standard object "operator", $person->getChildFamilies() calls the "getChildFamilies()" method in the $person object/instance of the class "Person". http://php.net/manual/en/language.oop.php http://php.net/manual/en/language.oop5.php

When you follow a link from the starting point, you're at a depth of 1. Every subsequent link you follow in that "thread" will increase the current depth. Set a limit for how deep the crawler is allowed to go.

When using mysql_num_rows(), you're never actually fetching the result data. if (mysql_num_rows($techMatch) > 0) # found existing tech { $techMatch = mysql_fetch_assoc($techMatch); //added $tNum = $techMatch['t_num']; }

My default/standard/unmodified Apache 2.x install is about 32 megabytes in size.

When $display['p'] is empty, you set $f to some html for an empty cell. When it is not empty, you set $file to a cell containing $display['p']. Finally you print neither $f nor $file, but $display['f'].
